Probably has to do with a script not assigning/removing a variable correctly. It has happened periodically to some of my PCs as well, but it does always seem to correct itself eventually. Haven't spent any time trying to find a manual fix, and I havent nailed down a common thread for the time that the behavior has been triggered... I seem to recall dying and going to the Great Hall seemed to be one trigger for it, but I don't think it was 100% repeatable.

It might be to do with the weather effects... cloudy/overcast or raining outside, the sun-damage scripts get turned off.... ... there are also "shadow-sections" in some cities (two that spring to mind are the path in the vale from the asis temple to the SDI and under the large tent in Calithia).... use.. erm... ;;info time (I think) to check on the time of the day, weather, and a bunch of other stuff I don't actually recall....

But that might be the issue... okay... back to lurking in the shadows as every good shadowchild should do.... love you all Aeneans
